4GRAIN- DOOR.

SPECIFCATION forming part of Letters Patent No. 266,084, dated October 1'7, 1882.

` Application timmy 22, 1882. (No motel.)

To all whom it may concern: g

Be it known that I, JACOB BRENZEL, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain-Doors, of which the following is a specification.

My invention relates to improvements in grain-doors for cars.

The object ot' my invention is to provide a grain-door for cars which shall be adjustable to suit different cars, and so arranged that the door, when in place, may be tightened up in such a manner that no grain will be permitted to leak through. To this end my invention consists in a construction and arrangement of parts, as hereinafter fully described with reference to the accompanying drawings, in which- Figure 1 is a front elevation View of my improved grain-door complete. Fig. 2 is an end view of the same. Fig. 3 is a sectional view of the same enlarged, and Figs. 4 and 5 are Views showing a modification in the construction thereof.

Similar letters refer to similar parts throughout the several views.

In the said drawings, A represents the door proper, to one end ot' which is secured-a cleat, b, in the ordinary manner.

B is a movable cleat, attached at the other end of the door by dovetail-shaped pieces (t ct, on which it slides. Extending from the stationary cleat b to a point beyond the center of the door is a piece, C, which is also secured to the door A, with one end resting against the stationary cleat b, and provided at the other end with a plate,p, through which projects the end of a rod, E, turned down at this point to form a shoulder, which rests against the plate 4o p, and is upset or riveted on the other side of the plate to prevent it from pulling through. This rod E at the other end extends through the adjustable cleat B, in whichis mortised a nut, c, into which the end of the rod E screws, both nut and rod being properly screw-threaded for this purpose.

Extending loosely through the rod E is a small handle-bar, e, provided at each end with a small knob, e', to prevent it t'rom falling out and becoming lost. This handle-bar serves to turn the rod E in either direction, and also prevents it from turning or becoming loosened by the motion of the car.

The door A is intended to be placed in position in the car in the ordinary manner, the adjustable cleat B being rst moved to suit the size of the car-door by turning the rod E in either direction, which, by screwing into or out of the nut c, moves .the said cleat backward or forward on the slides a a. After the door is properly in place the rod E may be turned until both cleats press tightly against the opposite door-jams, making a perfectjoint,

Which will prevent any leakage ot' grain.

Instead of using the slides a a, the cleat B may be attached to the door A by screws s, which pass through slotted holes h therein, as shown in Figs.4 and 5; or they may be attached in any other appropriate manner with the sarne result.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a car grain-door, a stationary'cleat, b, and a movable cleat, B, provided with a nut, c, in combination with a screw-threaded rod, E, substantially as and for the purpose set forth.

JACOB BRENZEL.
